He asked Olivia to explain exactly when the team had last seen the files.

"Thursday afternoon," she replied. "We finished the calibration tests, saved everything, and left. When we returned this morning, the folder contained an older version."

"Did anyone outside your team use the computer?"

"Several people used the workshop. But they shouldn't have had access to our project folder."

Marcus did not immediately assume that anyone had stolen the work. Files could disappear because of synchronization errors, accidental deletions, or mistakes during software updates.

He called the workshop coordinator, who contacted the volunteer responsible for maintaining the network.

Within an hour, they had checked the obvious possibilities.

The backup drive was working. The server had not experienced an outage. No scheduled maintenance had taken place on Thursday night.

The missing files appeared to have been removed through a valid account.

That detail changed the investigation.

The coordinator reviewed the access records and discovered that the files had been opened late Thursday evening, several hours after Olivia's team had left.

The account belonged to Marcus.

He stared at the screen.

"That's impossible," he said.

He had been at home that evening helping his younger sister, Lily, with a school assignment. He had not visited the workshop, and he had not logged into its network remotely.

The coordinator checked the authentication record.

The account had been used from a computer assigned to the workshop's administration desk.

"Could someone have left your account signed in?" Olivia asked.

"Possibly," Marcus replied. "But we shouldn't guess."

He requested that the coordinator preserve the access records and restrict further changes to the affected folder. He also asked everyone who had used the administration desk that evening to provide an account of what they had done.

The coordinator agreed, though the situation made her visibly uncomfortable.

The Open Bench Initiative had been created to give students a place where they could trust the people around them. Now, one of its first serious problems involved the possibility that someone had used a trusted account to remove a student's work.

Marcus understood that the damage could extend beyond a few missing files.

If Olivia's team believed their ideas could disappear without explanation, they might stop sharing their work. Other students could become reluctant to collaborate. The workshop could lose the very openness that made it valuable.

He returned to Olivia.

"We'll investigate this properly," he promised. "But until we know what happened, don't assume it was one particular person."

Olivia nodded, although her expression suggested she was already worried about something else.

"What is it?" Marcus asked.

She hesitated before answering.

"Two weeks ago, a man visited our workshop. He said he worked with a company interested in energy-monitoring technology. He asked a lot of questions about our device."

"Did he ask to see the software?"

"He asked how we calibrated the sensors. I explained the general idea, but I didn't give him our files."

"Do you remember his name?"

"Martin Cole."

Marcus wrote it down.

The name meant nothing to him, but the visit was worth documenting. He asked Olivia whether the man had identified the company he represented.

She shook her head.

"He said he was exploring opportunities. He didn't give us a business card."

Marcus thanked her and promised to follow up through the workshop's official procedures.

He did not tell her what he was beginning to suspect: the missing project might be connected to something larger than an ordinary computer problem.

That afternoon, Marcus called Dr. Evelyn Shaw.

She listened carefully while he explained what had happened.

"Do you think someone is targeting the initiative?" she asked.

"I don't know. But the files were accessed through an account that shouldn't have been used that way, and someone recently showed unusual interest in the project."

"Then preserve the records and don't investigate anyone's private accounts yourself. Let the network administrator document what the system actually shows."

"That's what we're doing."

Evelyn paused.

"Marcus, there's something you should understand. When a new program becomes successful, people start paying attention for different reasons. Some want to help. Some want to profit from it. Others simply want to associate themselves with its reputation."

"So we shouldn't trust anyone?"

"No. You should build a process that doesn't require blind trust."

The answer reminded Marcus of the Aegis Grid.

He thanked her and ended the call.

Later that evening, he returned to the workshop to collect his notebook. The building was quiet, and the last of the volunteers had gone home. As he passed the administration desk, he noticed a small envelope tucked beneath the edge of the keyboard.

His name was written on the front.

Inside was a single sheet of paper.

The message contained no signature and no explanation.

It read:

Stop looking for the missing files. The project was never yours to begin with.

Marcus read the sentence twice.

He felt a chill of uncertainty, but he refused to treat the message as proof of anything. Someone could have been trying to frighten him, provoke him, or make him accuse the wrong person.

He photographed the note, placed it in a clean folder, and notified the workshop coordinator.

Then he called his mother.

Denise listened without interrupting.

"Are you safe right now?" she asked.

"Yes. I'm at the workshop, and the coordinator knows about the message."

"Good. Don't handle this alone."

"I won't."

When he hung up, Marcus looked across the empty room.

The Open Bench Initiative had been created to give students opportunities that might otherwise remain beyond their reach. He had believed that providing equipment, mentors, and fair procedures would be enough to protect that mission.

Now he understood that the initiative would have to prove its values when doing so became inconvenient.

The next morning, he would begin documenting every detail of the missing project.

He had no idea that the investigation would lead him back to Caldwell Industries—and to a decision that could put the future of the entire initiative at risk.

PART 12 — The Man Who Knew Too Much

Marcus arrived at the Open Bench Initiative before the first students came through the door.

He had barely slept. The anonymous note remained inside a folder on the coordinator's desk, and the missing files had become more than a technical problem. Someone had apparently wanted him to stop asking questions.

But Marcus had learned from the Aegis Grid investigation that suspicion was not the same as evidence.

He began by writing down everything he knew.

The project files had disappeared between Thursday afternoon and Saturday morning. The access records showed activity through his account, using a computer at the administration desk. A man named Martin Cole had recently visited the workshop and asked questions about Olivia Bennett's energy-monitoring device. Finally, someone had left a warning addressed directly to Marcus.

Four facts. No proven connection between them.

At eight thirty, the workshop coordinator, Rachel Morgan, arrived carrying a laptop.

"I reviewed the access records again," she said. "There's something we missed."

She showed Marcus a list of file operations. The activity attributed to his account had taken place in a sequence that looked deliberate. Several folders had been opened, selected files had been removed, and the shared project directory had been restored to an earlier state.

"Could a synchronization error do this?" Marcus asked.

"Not in this sequence. But I still can't tell you who was sitting at the computer."

"Can we determine whether the files were copied before they disappeared?"
